Runner Cardio watch not re-charging
my Cardio Runner Watch has stopped re-charging.
When connected to the charger docking station, the watch screen shows the battery-charging image as normal. But when the battery fully-charged image appears on the screen and the watch is removed from the charger, the battery-empty image appears on the screen briefly, before it goes blank.
Also, the watch itself feels warm, as if the power is going into the watch circuit but not into the battery.
The watch is 2 years old, but up to now I've had no problems charging the watch, this problem has come out of the blue.
I hope you can help.
